textexpander macros

Generally, our understanding of C/C ++ macros is nothing more than two points: 1. It is used to process repeated inclusion of header files. 2. Macro used to define similar functions. Everyone can understand the first point. Second, we often see macros used to define similar functions. What is more classic: Define max (A, B) (A> B )? (A) :( B) A similar approach is primarily to bypass type checks, in this wa

Record macros in Word 2013 Step 1: Start Word 2013 and open the document, enter the text you want to work with in the document, and then, on the View tab, in the Macros group, click the Macro button and select the Record Macro option in the Open list, as shown in Figure 1. The Record Macro dialog box opens, you enter the name of the macro in the Macro Name text box, and you select the document that you save

You is a C programmer, you must is familiar with macros. They is powerful and can help you ease your work if used correctly. However, if you don ' t define macros carefully, they could bite you and drive you crazy. In the many C programs, you could see a special macro definition which may seem isn't so straightforward. Here is one example: #define __set_task_state (tsk, State_value) do {(tsk)->state = (stat

| _ ioc_write (bidirectional ).The kernel defines the _ IO (), _ ior (), Iow (), and _ IOWR () macros to help generate the above cmd. The following describes the implementation of _ IO (). Others are similar: You can see the definition of _ IO () in ASM-generic/IOCTL. h.: # DEFINE _ IO (type, NR) _ IOC (_ ioc_none, (type), (NR), 0) Let's look at the definition of _ IOC ().: # DEFINE _ IOC (Dir, type, NR, size )\(DIR) (Type) (NR) (Size) It can be see

description in section 6.10.3.1 of the standard is still clear, and it writes as follows: after the arguments for the invocation of a function-like macro have been identified, argument substitution takes place. A parameter in the replacement list, unless preceded by a # Or # preprocessing token or followed by a ## preprocessing token (see below), is replaced by the corresponding argument after all macros contained therein have been expande

Three macro tools I used in vc6 Favorites New article: Status Bar (3/3)-teststatusbar. Java implemented in Java | old article: Create a class for the filefilter object used by jfilechooser implemented by RegEx AlthoughHowever, the time to use VC is not short, but I recently noticed that the VC can also customize macros, such as Word and execel. I wrote the following three, which has a good effect and can greatly prolong the service life of the keybo

declare_dynamic macro to the Class header file, and then include this module in all. cpp files that need to access part class objects. If delcare_dynamic and implement_dynamic macros are used as described, you can use the runtime_class macro and cobject: iskindof function to determine the object class during running time. If declare_dynamic is included in the class definition, implemetn_dynamic must be included in the class tool. Declare_dyncreateDec

1. Question: C ++ rtti lacks some runtime information and cannot directly create an object based on the object name. To achieve serialization, MFC constructs its own rtti information from the ground up and defines a set of macros. For details, refer to the implementation of the following classes and Macros in the MFC source generation:Cruntimeclass, cobject, declare_dynamic, implement_dynamic 2. Requirement

Some predefined macros are specified in the C standard and are often used in programming. The following table lists some predefined macros that are frequently used. _ Date _ Date of preprocessing (string text in the form of "Mmm dd YYYY) _ File _ represents the string Text of the current source code file name _ Line _ represents the integer constant of the row number in the current source code. _ Time _

If DELCARE_DYNAMIC and IMPLEMENT_DYNAMIC macros are used as described, you can use the RUNTIME_CLASS macro and CObject: IsKindOf function to determine the object class during running time.

You can use macros to define "functions" without return values ". For example: # Define printmax (A, B)/do/{/INT x = A, y = B;/printf ("MAX: % d/N", x> Y? X: Y); //} while (0) //... printmax (3, 4 ); Such a "function" is essentially different from a function in the true sense, because a macro is a pre-compilation behavior and only replaces the text before compilation. In Python source code, we often see macro definitions similar to the following:

Part I: Macro basics A macro is simply a text substitution tool in the C preprocessing phase, which is not visible to binary code after compilation. The basic usage is as follows: 1. Identifier aliases #define BUFFER_SIZE 1024 preprocessing phase, Foo = (char *) malloc (buffer_size);//is replaced with foo = (char *) malloc (1024); Macro body wrapping requires a backslash at the end of the line #define NUMBERS 1, 2, 3 preprocessing phase int x[] = {numbers};//is expanded to int x[] = {1, 2, 3}; 2

How to use macros to print more data, have seen others do, in Excel, she set up a macro, there are a lot of data, names-address-telephone what, like a payroll list just along the distribution, no format. Then you can print it in a good format, only to realize that it is a macro. Excel on the DOT tool--macros--record a new macro, in the macro name that enter a name you know later. It can then be set to the

Some predefined macros in the C language standard The C standard specifies some predefined macros that are often used for programming.The following table is a list of predefined macros that are often used. __date__Date for preprocessing (string literals in the form of "MMM DD yyyy") __file__string literal representing the current source code file name __line_
